From other players' footage of IW4M, I have seen that in Private Match they have the new 4D1 maps (i.e. Burger Town, Contingency etc.) available to them under Bonus Maps. However, I don't have these maps available to me in Private Match. I know it's not a massive deal, but it's kind of annoying when everyone else seems to have the option when I don't. Does anyone know how I can get these maps to become available in Private Match? Thanks

Load them manually.

 

mp_nuked - Nuketown
oilrig - Oilrig
invasion - Burger Town
iw4_credits - It's Basicly A Cube
gulag - Gulag
contingency - Contingency
so_ghillies - Pripyat

 

In the game press ^ (key above tabulator) and type "/map [mapname]", without the "" and replace [mapname] with the mapname

Or you can do /ui_mapname mp_nuked and change the gametype and you're good.

Thanks for the help, now I can set up private matches with any map

You could also install this mod: viewtopic.php?f=17&t=20582

The new maps will be shown in the menu
